The Highway: Trapped in Spaghetti

You are tooling along the superhighway
when the signs suddenly begin to snap up before your eyes. You want to
get off at the interchange. But where? There it is -no -yes -better
hurry -and you spin into the cloverleaf with the sickening feeling
that you're probably wrong and doomed to go miles out of your way.

The brand-new Pook's Hill Inter change near Bethesda, Md., is
different. There you can be absolutely certain that
you're wrong. They left
out half the exit ramps.
